Improvement in pumps

JACOB GOODYEAR, OF CARLISLE BOROUGH, PENNSYLVANIA.

IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 53,810, dated April 10, 1866.

To all whom it may concern:

Beit known that I, JAcoB GOODYEAR, of the borough of Carlisle, county of Cumberland, and State of Pennsylvania, have invented a new and useful Improvement in Pumps; and I do hereby declare that the followingis a full, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawings, making a part of this -,pecication, in which- Figure l is a perspective view of the pump, and Fig. 2 a view of the ring used as packing.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

To the side of the well or an upright, F F', I fasten two hollow cylinders, A and A', at a perpendicular distance from each other proportioned to the depth of the well or the height to which the water is to be raised. The diameter of the cylinder A is twice as large as the diameter of the cylinder A'.

The perpendicular space between A and A' is occupied by two hollow cylinders, B and B', jointed at D D. The diameter of B and B' bear the same proportion to each other as the diameters of A and A', but the diameters of the cylinders B and B' are so much less than the diameters of the cylinders A and A' as to permit the cylinders B and B' to be inserted in the cylinders A and A', with a space of an inch or more remaining between the outside of B and B' and the inside of A and A'. These two spaces are filled with the india-rubber rings C and C'.

At m m' are rims to obviate the possibilit-y of the rings C and C' passing over the ends of the cylinders B and B'.

At a a' and b b' are t-wo valves opening upward.

The plunger, composed of the two cylinders B and B', jointed at D D', is elevated and lowered by the ordinary hand pump-lever, or by any other power to the same en d which may be desired.

The pump thus constructed will throw a continuous stream and require less power than vthe pumps in use, because the rings C and C' change the ordinary sliding friction into rolling friction. The manner in which a continuous stream is thrown is at once apparent without going into any demonstration of it.

What I claim as my invention, and for which I desire to secure Letters Patent of theUnited States, is-

The combination and arrangement of the cylinders A and A', B and B', the valves a and a', the rims m and m', and the india-rubber rings C and C', as and for the purposes set forth and describe JACOB GOODYEAR. Witnesses: A. DE HUFF,
